'and the other being locked u the' bottom ef This invention relates tograted windows and more especially to windows having slid ing sashes towhich may be secured bars. The object of the invention is to supply thei opening of the window, when the lower sash is raised'or the upper sashis lowered, vwith bars to prevent the entrance of would-be 1ntruders. lA further object of the invention is the l -release and discarding ofthe bars when they This is accomare found unnecess plished b mountingall of the bars on a horizonta strip or rod that is adapted to be locked'or otherwise secured to the bottom 5 rail yof the'lower sash and tli'etop rail of the upper sash and may be released byl means of a key, orimmediately attached again. l

These and other details and ob'ects of the invention are more fullydescribe in the following specication, set forth in the appended cla1msand illustrated in the accompanyvin drawings, wherein:

Figure 1 is a perspective view of a window from the interior with thetwo sashes partly opened and the openings filled with the grating. Y

Fig. 2 is a face view of the inside of the window with the upper sashclosed and the lower grating released. j

. Fig. 3 is a detail sectional view showing the operation of the lock.

Fig. 4 is a cross sectional view of Fig. 8. Fig. 5 is a detailperspective view of a part of the grating. 1

As best shown lin Fig. 2 thee-window may present the appearance of anordinary frame and sashes when itis desired to dispense with the gratingand protecting means which although not in sight may be made limmediatelavailable. Y

In' ig. 1 the sashes 5 and 6, being respectively the upper and lowersliding members of the window, are provided with gratings that comprisethe metallic strip or rod' 7 and the bars 8 located at a right angle toeach other, the ends of the-bars entering perforations yin the rods' andbeing welded or swa ed together, both the lgratings being identical butthe position of the bars and rods are re-l versed, one being on the-t'op of the sash 5 sash 6. Y A

The walls of the building above and below the window frame are providedwith suitable recesses below the sill and above the head of said frameand into which` the bars 8 run when the windows are closed while therods 7 have suitable recesses into which they rest when the sashes areclosed, one ofA these recesses. 9 being shown in Figs.'3 Vand 4 in thewindow sill 10. The rodsv 7 n are secured to the sashes by meansof thelocks 11, shown more clearly in Fig. 3 as being a type commonly used indisks and having the vlaterally operating bolts 12, with a guard 13,that enter the slot 14 of the rod '7 andv sprin outward and preventretraction of the' loc until a key is inside. Both o ff the sasheshavekey holes -15 iso ii'ord a means for the operatlon of the By thismeans the lower grating may be left on the sill 10 andthe bars in theirrecesses as shown in dotted lines in Fig. 2.

The upper grating may also be released fand retained 'in its elevatedposition by means of an eye 16 that enters a recess in the window frameand a pin 17 may be passed through the frame and eye when the gratingis' unlocked and released and the u per sash may bel lowered, leaving anunolistructed opening above it.

It is obvious that equivalent means may be adopted to hold the uppergratingin its elevated position when released from its sash and, thatlother means than the lock shown may be resorted to, also other.arrangements and modifications may be used Without departing from theessential features above described orfrom the scope/of theappendedclaims. .v

. What. I claim las newiisr 1. In gratedwindows, the combination ofwindow` Sashes having locks at their closing edges, a window framehaving recesses above theupper sash and below the lower sash,

and 'rods carrying vertical bars and adapted to iitin' the recesses andhaving each a slot into which the bolts of the locks may enter andengage said rods.

2. In grated windows, the combination of a window frame having recessesat its top and bottom, an' upper sash below the top recess, a. lowersash above the lower recess,

rods having vertical bars and adapted to lie in the recesses and havingeach a. slot, locks on the sashes and adapted to enter the slots so thattheir bolts will enga-ge the bars, and

'an eye on the upper ro@ ,'ith a. pin to hold it in the upper recesswhen the lock is disengaged.

In testimony whereof I hereunto ax my signature.
